The objects of our invention are to provide jacent to the tracti ro a cor" -planter,in which there is a mechanism two collars 1 for rigidly 4securing the driving-shaft of the their outer faces de ,planter 'fo the traction-wheels thereof, and, the inner faces ofthe t further, to provide means for hrowing both 12, respectively, f

Mflln shaft or axle. 10,- between the side 19`of the l gear constituting a with the gear 32 that by o frame and the bar 28, is' the gear 30, said driving connection between the traction-wheels and the belt. Mounted in the bar ame is a shaft 31, on which is mounted the gear 32 in mesh with the gear 30. Secured to the gear 32 'in such a way that the gear is ee tol rotate is the lever 33, which is pivotally secured to a lug 34, attached tothe frame 's ever is so arranged and connected' Aerating itthe gear .32 may be thrown out 0 operative relation with the -gear 30 against the resistance ofl a 'for t At the forward end of the frame there isa" spring ,35, which is mounted on the shaft 31 and is designed to normally hold the gear 32 in position on the shaft, where itis in operative relation with the gear 30.

Mounted on the inner end of the shaftl 31 is a sprocket-Wheel36. Pivotally connected' with the cross-bar 27 is a sprocket-idler 37, and a spring 38, which is attached to the'bar 28, supports this idler in the proper position e purposes hereinafter made clear.

4bar 39, upon the forward side of.l which is mounted the sprocket 40. Passing around the sprocket-wheels 36, 37, and 40- is a sprocket-chain 41, having a number'of operating-lugs 42 secured' to it at equal distances from each other. As this chain is driven the sprocket-idler' 37, which is maintainedby the spring 38, constantly holdsthe chain 41l taut as .it 1s beingdriven andv takes up any slackin this chain. A cross-bar'43 is mounted adj ai cent tothe forward end ofv the frame 1'0 and substantially parallel with the bar 39.

Mounted at the ends 'of the bars 39and`43 are the two boxes or .hoppers 44' and 45, in which the corn is placed for planting beneath which the runners .or furrow-openers 46j and 47, respectively,'are attached. A shaft 48 is I mechanisms in the boxes 44 provided, which extends across the forward end of the frame between the cross-bars 39 and 43, to the ends of which the dropping and 45 (not shown) are operatively connected.. Rigidly secured to the shaft 48 and midway between its ends is a forked operating-lever 49, between the tines of which the chain 41 is designed to pass as it is operated. As the chain 4,1 is driven the lugs 42 engage the tines of the lever 49 and move the lever forwardly against the resistance of the spring 50 (which maintains the lever' 49 at its inner limit of movement) and causes the shaft 48 to be rocked and operate the dropping mechanisms in the boxes. It will be seen on account of the fact that the lugs 42 are spaced equidis- .tant on the chain 41 the dropping mechanisms will be operated as this c ain travels a predetermined' distance, and therein line with eachother.

On account of thefact that the driving- 28 and the side 119 of thel shaft 10 is constantly held stationary' relative to the traction-wheels neither of the traction-wheels can travel faster than the other.

.Attached to each sidey of. each of the runners 46 and 47 is a guard 51, which are designed to-engage the surface of the ground. as the machine is advanced over the groundsurface and'force clods of earth coming in the path of the runners to the side of row, and thus prepare the earth so that the wheels which pass ver the hills of" corn which have been covered up.

In practical'o eration and assuming that two rows have driving-shaft is secured to the tract/ionwheels 11 and 12 and the end of the row is reached, the operator operates the lever 26 to throw the collars 13 and 14' out ofengageh ment with the'traction-wlieels 1v1' and- 12, so` that these wheels can rotate freely on the shaft IO'in making the-turn, andlience throw the 'entire device out of' operative relationl with the traction-wheels. When the next two rows are reached andthe operator is ready to throw the operative parts of theelevice into operative relationto the traction\ wheels, hereleases the l'everl 26, andthe device is iii-readiness forull operation. However, before le commences to'loperate4 the planter on the next two rows he throws the gear 32 out of enga ement'with the gear 31 and by adjusting t e chain- 41l places the dropping mechanism in proper position, so that it' Willo erate to drop the cornx in line with the two 'lls in the preceding rows last planted. He then throws the-gear 32 into operative relation with the-gear 30'and proceeds with the-planting.
